One embodiment of the system is characterized by flexible plastic in a tubular shape with only one opening, which creates a water tight seal between the appendage and the system. The mid-section torso embodiment also has an optional pocket on the inside surface (facing the skin) a pocket for housing a medical device such as an insulin pump or pocket health monitor. Also described is process for making and using the system.

BACKGROUND

This disposable cast and IV medical shower system of this invention relates to methods, devices, and system for protecting a patient with a cast or wound with or without a bandage, or an Intravenous (IV) therapy line or drain line attached to an appendage from getting the cast, bandage, wound, drain line or IV site wet during a shower or bath. More specifically this device allows the patient to independently maintain personal hygiene without the need of a nurse or assistant, and without the worry of damaging the medical implements or creating infection due to the water from the shower.

THE PROBLEM

The problem with prior art cast covers designed for bathing and showering is that they tend to be expensive to manufacture and package, and include a hard bulky circular mechanism for securing the device onto the protected appendage. While this hard circular mechanism is necessary to secure the device it reduces patient flexibility as well as increases production and shipping costs. Prior art devices are also not disposable. This invention eliminates the need for this securing mechanism thereby reducing production cost, shipping cost, and cost to the customer.

SUMMARY

The cast and IV medical shower system is a watertight system designed to protect patients with casts, wounds with or without bandages, and/or intravenous (IV) therapy sites or drain lines on their hands, arms, feet, legs, or other limb, body part or appendage from getting the limb or body part wet during a shower or bath. A Cast and Intravenous (IV) Medical Shower System for protecting casted and/or IV therapy injected appendages from moisture while a patient is showering. Pluralities of embodiments are disclosed. One embodiment of the system is characterized by flexible plastic in a tubal shape with only one opening, which creates a water tight seal between the appendage and the system. The mid-section torso embodiment also has an optional pocket on the inside surface facing the skin for housing a medical device such as an insulin pump or pocket health monitor. The invention reduces the risk of infection to the appendage or damage to a protected cast or bandage by eliminating the chance of water infiltration.

PRIOR ART

A prior art search was not commissioned because the inventor is intimately familiar with the prior art. A prior art patentability search was neither commissioned nor conducted by the inventor, but the inventor is intimately familiar with the prior art. Many inventors have designed protection devices to keep cast, bandages, and IV connections dry and hygienic during patient showers, however none of the prior devices include the flexibility, simple ease of use, reliable water seal, durability, affordability, and disposability of the current invention.

The solution provided by the present inventor is elegantly simple, cost effective, and intuitive. Prior art devices include ordinary plastic bags secured to the appendage in various ways, inflatable cast covers made of latex or similar material, and waterproof cast covers with hard bulky securing mechanisms. Following are typical examples of the prior art known to the applicant and/or his attorney arranged in reverse chronological order, with most recent first for ready reference of the reader.

No. 4,363,317 earned by Daniel Broucek of Grand         Raapids Mich. on Dec. 14, 1982 for, “Watertight Cast Cover”     -   e) United States non-Provisional Utility Patent 4,043,326         honorably granted to Little et al on Aug. 23, 1977 for         “Waterproof Cast Protector”

DISCUSSION OF THE PRIOR ART

Prior art cast covers also include air-casts that must be stretched over the existing casts and inflated to prevent water from entering. One problem with these inflatable devices is that while they may be suitable for patients with bandages and casts they are not suitable for patients undergoing IV therapy.

Other problems with the inflatable covers is that due to their inflatable nature they are subject to puncture from sharp fiberglass cast threads or even fingernails, they are hard to clean for a patient with a casted arm, and they are often made of latex which may cause an allergic reaction to some users.

The present invention overcomes the limitations of the prior art because it is not puncture-able when used correctly, and is made of hypo-allergenic material so is less likely to cause an allergic reaction to the user. This invention is also less expensive to manufacture than the prior art, and is a lower priced disposable alternative that does not require cleaning.

Prior art cast covers also include the use of ordinary plastic bags secured over the appendage. This method of cast covering often does not create the waterproof seal required by the user, does not fit the protected appendage well, and is not durable enough to be used more than once.

Additionally, prior art IV therapy site covers do not accommodate patients that also have casts or bandages on the same appendage, and prior art cast covers do not allow for the protection of IV therapy sites. This invention creates a waterproof seal around a patients IV therapy site and any cast or bandage on the same appendage. Prior art devices are also typically not disposable.

None of the prior art devices singly, or in combination, provides most of the features and objectives established by the inventor for this system as enumerated below. At least one of the objects is met in whole or in part by this invention.

The elastic band 613 is ultrasonically welded to the plastic protective cap 625 creating an opening hole 615 that is smaller than the diameter of the patient's head.

This embodiment of the system is also characterized by flexible plastic in a tubal shape with only one opening, which creates a water tight seal between the appendage and the system. Since some of the components of this invention such as head embodiment 600 are amenable to injection molding process, the inventor is please to provide the following description to complete the teaching for a person of average skill in the art.

Injection molding is a process that has been in use since the 1920s and provides versatility almost unmatched in the mass production of any material. It requires that melted plastic be forcefully injected into relatively cool molds. As the plastic begins to harden, it takes on the shape of the mold cavity and, when cool, requires few post molding operations. Other advantages of this process include its speed of production and the ability to simultaneously manufacture multiple parts.

Blow molding in the production of plastic shapes is a form of extrusion, a major technique in the plastics industry. Extrusion is used to push a molten tube, called a parison, into a bottle-shaped mold. Compressed air then forces the parison against the cold walls of the mold, hence the term “blow molding”. Molds are generally side fed, with the thickness controlled by a tapered mandrel (core) or a variable-orifice die.

Continuous extrusion is possible by the use of multiple blow molds. Potential problems that might arise during the development of Safe-N-Sound should be amenable to resolution through normal product testing and refinement processes, after which we would anticipate the product, could be produced routinely. However, we also recommend that an interested company should be allowed to do their own form of testing and marketing and to provide modification suggestions.

Assembly Use and Operation

The use of this invention is very simple even intuitive because it comes in a variety of shapes that are approximately the same as the appendage it is designed to protect. An appendage in need of shielding is placed in the opening of the device and the device is then extended along the length of the appendage. Another embodiment of the system is characterized by flexible plastic in a cylindrical shape with openings on both ends. Embodiments of this invention can also include an IV window opening in the cylinder wall for the extension of the IV Insert. All openings of this embodiment are ultrasonically welded with elastic to create a water tight seal when in use.

The embodiment of the invention used for protecting IV therapy sites on a patient includes the optional IV therapy window (119, 219 . . . etc) as illustrated in FIG. 1A, FIG. 1B, FIG. 2A, FIG. 2B, FIG. 5A, and FIG. 5B. The IV therapy window is created by cutting a rectangular section out of the protective sleeve. A strip of polyurethane film is then ultrasonically welded to cover the rectangular section. A small hole (120, 220 . . . etc) is then placed in said polyurethane film to allow access for the IV therapy tubing. The IV therapy window is an optional part of this invention.

Typically this invention is single use disposable type. It can be made in a variety of sizes and colors to suit the needs and aesthetics of everybody including, children ladies and elderly.

The IV therapy window (119, 219 . . . etc) of this invention is used as follows. Before applying the invention to the appendage the patient's intravenous tube is first disconnected from the supply line and sealed using a heparin lock. The IV insert is left in place the patient's appendage remains in place. The protective sleeve (111, 211 . . . etc) is placed over the appendage receiving the IV therapy. The upper most opening hole (115, 215 . . . etc) is expanded and placed over the IV insert. The end of said IV insert is maneuvered from inside the protective sleeve (111, 211 . . . etc) to the outside of said protective sleeve (111, 211 . . . etc) through the hole (120, 220 . . . etc) in the IV therapy window (119, 219 . . . etc). The diameter of said hole in the IV therapy window hole (120, 220 . . . etc) is smaller than the diameter of the IV insert tube, allowing the window to conform to the shape of the tube and creating a waterproof seal.

The seal at the opening hole (115, 215 . . . etc) of the invention are also waterproof allowing the patient to take a shower without fear of wetting or damaging the connection between the IV Insert and the arm. Any cast or bandage on the patient's arm will also be shielded from water when this embodiment is applied over it. The waterproof seal can be readily manufactured with ultrasonic welding technology well known to a person of average skilled in the art.

The device has a multitude of sizes so that it can fully cover appendages on a variety of body types. The term appendage as used herein refers to a forearm and arm (upper appendage), leg and thigh (lower appendage), neck, midsection or torso, and head. The full cover cast protecting embodiment of the hygiene system can also be used to protect bandaged areas that are required to stay dry. This embodiment of the invention has a tubular shape with an opening only on one end. The closed end of the system is either mitten shaped or sock shaped, to fit over the user's hand or foot. The main portion of the system is made of plastic, with an elastic band ultrasonically welded to the plastic at said open end. The elastic portion of the invention creates an opening at said end with a diameter that is much smaller than the diameter of the protected appendage when not in use.

When the casted appendage is placed in the system through said end said opening conforms to the size and shape of the appendage creating a watertight seal. The length and size of the protective sleeve of the invention can vary depending on the appendage protection desired. Medical shower systems for use on the arm can range from finger-to-wrist length to finger-to-shoulder length. Hygiene systems for use on the leg can range from toe-to-ankle length to toe-to-full leg length.

A partial cover embodiment of this system can be used for keeping an appendage dry while allowing the user the unhindered use of their extremities. When used on a patient's arm this embodiment can be of any length to secure dryness from the patient's wrist up to the patient's shoulder. The partial cover embodiment is similar to the full cover embodiment with the exception that there are openings on opposite ends of the system.

The additional opening gives the system an open tubular shape. As in the full cover embodiment the openings of the system are expandable, but initially smaller than the diameter of the covered appendage, allowing the partial cover to be placed on an arm in a sleeve like manner and producing a waterproof seal.

This embodiment can also be enlarged appropriately to meet the dimensions of a user's leg or torso. This embodiment will also range in length so that only the necessary portion of the appendage is covered. When used on the patient's leg this embodiment can be of any length to secure dryness from the patient's ankle to the patient's upper leg.

The IV protecting embodiment of this invention has a design such that a waterproof seal is created over a cast or bandage and an IV therapy site, while still allowing the user access to the IV tubing. The IV protecting embodiment has the same shape as either the full cover or partial cover embodiments with an additional opening along the cylindrical wall which serves as an IV window.

The IV window is made by placing a hole in the cylindrical wall and ultrasonically welding a polyurethane film to cover said hole. Said polyurethane film has a small opening in the center for the passage of the IV tubing sealed by a Heparin Lock (Hep-Lock). The patient's appendage and attached IV tube are inserted through the first opening hole in the protective sleeve. In a partial cover embodiment the patient's extremities are extended through the second opening hole. The IV tube is extended from within the interior of the protective sleeve to the exterior of said protective sleeve through a small hole in the polyurethane film of the IV window. Said small hole in said polyurethane film has a diameter that is less than the diameter of the IV tubing. When said IV tubing is inserted through the IV window the polyurethane expands to accommodate said tubing and a watertight seal is created.

The applicant has described the essence of this invention.
